In this report we reveal the presence of significant variations in Brønsted catalytic activity within and between individual H-ZSM-5 zeolite crystals. Fluorescence microscopy in combination with a fluorogenic probe was used to resolve the catalytic

The performance of zeolites as solid acid catalysts is strongly influenced by the accessibility of active sites. However, synthetic zeolites typically grow as complex aggregates of small nanocrystallites rather than perfect single crystals. The struc

Photoluminescence (PL) of organometal halide perovskite materials reflects the charge dynamics inside of the material and thus contains important information for understanding the electro-optical properties of the material. Interpretation of PL blink

Structural and temporal inhomogeneities can have a marked influence on the performance of inorganic and biocatalytic systems alike. While these subtle variations are hardly ever accessible through bulk or ensemble averaged activity screening, insight
